What Customers Are Saying

Customers overwhelmingly praise these deck supports for their ease of installation, lightweight design, and superior durability. Most highlight how simple setup is—simply level the ground and place blocks with no digging, tools, or expertise required. Many note they can carry stacks of 10 with ease, making solo projects manageable. Reviewers consistently confirm the blocks securely support 4x4 posts and beams for decks, sheds, and ground-level structures. Made from recycled plastic, they resist cracking and shifting under load. A few mention cost concerns, but most consider them an excellent investment for convenience and reliability.

Not available in all stores

Would Recommend

Product allows me to keep my 4x4 posts close to the ground versus standing them on cement blocks that are about 8 inches thick. I don’t know how well they would work for a long fence. I suspect they wouldn’t be as stable as cement ones. I’m using them for a short fence (about 8 feet long). The downside is they are more expensive than cement ones.

Smaller Size than Camo Block

Would Recommend

I liked the smaller footprint that this one has...the other one (Camo Block) is larger and I didn't have enough room for them near each other, so I alternated between the two kinds. That worked well for me

They are not cheap but are very strong.

Would Recommend

Purchased TuffBlocks rather than concrete blocks, as used in the past. Liked the lighter weight, ability to shift around the deck frame and nice height to them.
